Step-by-step explanation:
1. let the angles of a triangle be x, 3x, 5x
sum of angles of triangle = 180°
x+3x+5x=180°
9x=180°
x=180°/9
x=20°
So, the angles are 20°, 60° and 100°
2. let the angles of a triangle be 2x, 3x, 4x
sum of angles of triangle = 180°
2x+3x+4x=180°
9x=180°
x=180°/9
x=20°
So, the angles are 20°, 60° and 100°

Step-by-step explanation:
1) let us consider the common multiple as x
x + 3x + 5x = 180°
9x = 180°
x = 180/9
x = 20°
1st angle = x = 20°
2nd angle = 3x = 3 * 20 = 60°
3rd angle = 5x = 5 * 20 = 100°
2) let us consider the common multiple as x
2x + 3x + 4x = 180°
9x = 180°
x = 180/9
x = 20°
1st angle = 2x = 2 * 20 = 40°
2nd angle = 3x = 3 * 20 = 60°
3rd angle = 4x = 4 * 20 = 80°
